This section GB/T 17631 Part of.

This part identical with ISO 6743-99:2002 "Lubricants, industrial oils and related products (L class) classification - Part 99. Total Groups "(in English).

This Part replaces GB/T 7631.1-1987 "Lubricants and related products (L class) classification - Part 1. Generic Packet." this section compared with the GB/T 7631.1-1987, the main changes are as follows.

--- Standard name was changed to "Lubricants, industrial oils and related products (L class) classification - Part 1. Generic grouping";

--- S Class deleting "special lubricant applications." Appendix A of this section is an informative annex.

This part of the National Standardization Technical Committee on products and lubricant oil (SAC/TC280) proposed.

This part of the jurisdiction of the China Petroleum and Chemical Corporation.

3 Symbols Explanation

3.1 A detailed breakdown of each group is based on the set of main applications required by the range of products and determined. The following table shows the breakdown of the class L 18 packets of the case.

3.2 Each product consists of a set of symbols with letters to represent.

Note. The first letter of the set of symbols representing respective groups of products, while behind the letters alone meaningless.

Full name of each product but also additional GB/T 3141 or specified viscosity grade grease NLGI consistency grade (see Appendix A).

3.3 In this classification system, the product name in a unified manner, for example, a particular product can complete the following form name, namely.

GB/T 7631.1-2008/ISO 6743-99:2002
